mysql -u root -p 提示:

mysqladmin: CREATE DATABASE failed; error: 'Access denied for user ''@'localhost' to database 'cacti''

原因是mysql的密码有问题

用mysql匿名用户可以进入数据库,但是看不见mysql数据库.

解决办法:

具体操作步骤:
关闭mysql:
# service mysqld stop
然后:
# mysqld_safe --skip-grant-tables
启动mysql:
# service mysqld start
mysql -u root
mysql> use mysql
mysql> UPDATE user SET Password=PASSWORD('xxx') WHERE user='root';
mysql> flush privileges;
mysql>/q

到这里密码已经修改成功,

mysql -u root -p
